The GPS 48 provides steering guidance and navigation
information using degrees, a measurement measured in a
clockwise direction from a north reference. North is described
as 000º, east as 090º, south as 180º, and west as 270º. The
diagram and compass rose below provide a graphic illustration
of the navigation terms used by the GPS 48. More information
on basic navigation and GPS are available at your local library
or bookstore.
